The `terraform refresh` command reads the current settings from all managed
remote objects and updates the Terraform state to match.

The `terraform refresh` command reads the current settings from all managed
remote objects and updates the Terraform state to match.

~> _Warning:_ This command is deprecated, because its default behavior is
2021-04-07 21:25:59 +02:00
unsafe if you have misconfigured credentials for any of your providers.
See below for more information and recommended alternatives.

2021-04-07 21:25:59 +02:00
This won't modify your real remote objects, but it will modify the
2021-12-15 03:41:17 +01:00
[Terraform state](/language/state).
2014-07-24 18:02:10 +02:00
2021-04-07 21:25:59 +02:00
You shouldn't typically need to use this command, because Terraform
automatically performs the same refreshing actions as a part of creating
a plan in both the
2021-12-15 03:41:17 +01:00
[`terraform plan`](/cli/commands/plan)
2021-04-07 21:25:59 +02:00
and
2021-12-15 03:41:17 +01:00
[`terraform apply`](/cli/commands/apply)
2021-04-07 21:25:59 +02:00
commands. This command is here primarily for backward compatibility, but
we don't recommend using it because it provides no opportunity to review
the effects of the operation before updating the state.

## Usage
2019-12-10 20:06:06 +01:00
2021-04-07 21:25:59 +02:00
Usage: `terraform refresh [options]`
2017-04-04 19:48:59 +02:00
2021-04-07 21:25:59 +02:00
This command is effectively an alias for the following command:
2017-04-04 19:48:59 +02:00
2021-04-07 21:25:59 +02:00
```
terraform apply -refresh-only -auto-approve
```
2017-04-04 19:48:59 +02:00
2021-04-07 21:25:59 +02:00
Consequently, it supports all of the same options as
2021-12-15 03:41:17 +01:00
[`terraform apply`](/cli/commands/apply) except that it does not accept a saved
2021-04-07 21:25:59 +02:00
plan file, it doesn't allow selecting a planning mode other than "refresh only",
and `-auto-approve` is always enabled.
2017-04-04 19:48:59 +02:00
2022-03-14 17:18:45 +01:00
Automatically applying the effect of a refresh is risky. If you have
2022-03-14 17:18:54 +01:00
misconfigured credentials for one or more providers, Terraform may
2021-04-07 21:25:59 +02:00
be misled into thinking that all of the managed objects have been deleted,
2022-03-14 17:18:50 +01:00
causing it to remove all of the tracked objects without any confirmation prompt.
2019-03-06 15:25:36 +01:00
2021-04-07 21:25:59 +02:00
Instead, we recommend using the following command in order to get the same
2021-07-28 15:40:07 +02:00
effect but with the opportunity to review the changes that Terraform has
2021-04-07 21:25:59 +02:00
detected before committing them to the state:
2015-03-27 23:24:15 +01:00
2021-04-07 21:25:59 +02:00
```
terraform apply -refresh-only
```
2014-07-24 18:02:10 +02:00
2021-04-07 21:25:59 +02:00
This alternative command will present an interactive prompt for you to confirm
the detected changes.
2021-03-25 00:17:03 +01:00
2021-04-07 21:25:59 +02:00
The `-refresh-only` option for `terraform plan` and `terraform apply` was
2021-05-26 18:09:39 +02:00
introduced in Terraform v0.15.4. For prior versions you must use
2021-04-07 21:25:59 +02:00
`terraform refresh` directly if you need this behavior, while taking into
account the warnings above. Wherever possible, avoid using `terraform refresh`
explicitly and instead rely on Terraform's behavior of automatically refreshing
existing objects as part of creating a normal plan.
